AKHQ vs Offset Explorer

AKHQ vs Offset Explorer, compared

F1 Kpow, AKHQ and Offset Explorer, side by side

Kpow AKHQ Offset Explorer

Adding an engineerDoes the bill stay flat when somebody joins?Yes. No change up to the 100 users included with each cluster, because the licence counts clusters and not seats. Yes. No change to the bill. No. Another named licence. A machine several people share needs one for each of them.

Staying currentDo updates come with the licence rather than as a separate charge?Yes. The published price is the annual per-cluster licence. No separate maintenance or upgrade fee is published, and upgrading is a container image swap because Kpow keeps no state. Yes. Upgrade the container. No. 365 days of support and maintenance are included, then 46 US dollars per licence a year.

Where it runsDoes it run as a shared server rather than on each engineer's machine?Yes. A single container serving a web UI, so the whole team works against one deployment rather than an install on each machine. Yes. One JVM container reaching one cluster or many, deployed by Helm. No. An installed desktop application on each engineer's machine, on Windows, macOS or Linux.

Who it authenticatesDoes the tool authenticate people rather than only the connection?Yes. People. LDAP, SAML, OpenID and OAuth2 with Okta, Microsoft Entra ID, Keycloak and AWS SSO, and role based access control per user and per resource. Enterprise. Yes. People, with LDAP, OIDC and HTTP basic, plus external role and claim mapping. No. The connection only. The documented authentication is client to broker, so the application holds no user identity.

Governance surfaceIs governance set per role rather than as global configuration?Yes. Role based access control at the global and the resource level, with multi-tenancy and server side masking policies, so governance is set per role rather than as one global file. Enterprise. No. Masking in four modes and opt-in audit events written to a Kafka topic, both configured globally rather than per role. No. No RBAC, no audit logging and no data masking on the feature list. ACLs are managed from the command line tool.

ConfigurationDoes the configuration live in source control rather than per workstation?Yes. Environment variables on one container, so the cluster list and the access model sit in source control with everything else. Yes. YAML under Helm, so the cluster list and the access model sit in source control. No. Per workstation, exported and imported between engineers as files.

Pricing unitA unit of sale, not a pass or a fail.Not a yes or no. Per cluster. Enterprise starts at 4,500 US dollars per cluster per year with 100 users included, and Community Edition is free. Not a yes or no. Free, Apache 2.0, with no paid tier and no commercial support. Not a yes or no. Per named user: 139 US dollars each at 1 to 10 users, 128 at 11 to 20, 119 at 21 to 50, and no published price above that.

Free useIs the software free to use at any team size?No. No. Community Edition is free at up to 3 clusters and 10 users, and Enterprise is a commercial licence starting at 4,500 US dollars per cluster per year. Yes. All use, with no licence to buy. No. Personal use only, with no time limit. Commercial, educational and non-profit use need a purchased licence after a 30-day evaluation.

Kpow meets 6 of 7 requirements on this page. One row is not a yes or no question.

Key takeaway

AKHQ is free under Apache 2.0 with no paid tier, and Offset Explorer is licensed per named user at 139 US dollars each for the first ten. AKHQ is one container a platform team deploys once, reaching one cluster or many, configured in YAML under Helm. Offset Explorer installs on each engineer’s own machine, and its documented authentication is client to broker only, so nothing authenticates a person and there is no identity for an audit trail to key on. Kpow by Factor House is licensed per cluster at a published price.

What is AKHQ?

AKHQ is an open-source Kafka management UI under Apache 2.0, formerly KafkaHQ, self-hosted and built on Micronaut. One deployment reaches one cluster or many, covering topic browsing, live tailing, producing, consumer groups, Schema Registry, Kafka Connect, ACL management and role-based access with LDAP and OIDC. There is no commercial edition, no hosted service and no paid support tier, and no feature is held back from the open release.

What is Offset Explorer?

Offset Explorer is a GUI application for managing and using Apache Kafka clusters, installed on an engineer’s own machine rather than deployed as a service. It runs on Windows, macOS and Linux, with a bundled JRE on the first two and Java 21 or later required on Linux. It was renamed from Kafka Tool and the vendor’s domain is still kafkatool.com, so the two names refer to one product. It is built by DB Solo, LLC, licensed per named user, and supports Apache Kafka 0.11 and above.

It is not a thin viewer, and the licence buys a vendor with support and maintenance attached to it.

What is the official 2026 pricing of AKHQ and Offset Explorer?

AKHQ costs nothing to license, and its whole cost is operator time. Somebody sizes the JVM, reads the issue tracker before an upgrade, and answers for it when it stops. There is no SLA, because there is nobody to escalate to.

Offset Explorer publishes a per-user ladder. One to ten users is 139 US dollars each, so five engineers is 695 US dollars. Eleven to twenty is 128 each, so twenty engineers is 2,560 US dollars. Twenty-one to fifty is 119 each, and above fifty there is no published price. Every purchase includes 365 days of support and maintenance, after which staying current is 46 US dollars per licence a year. The unit is the named user, so the bill tracks headcount and not cluster count, and a machine several people share needs a licence for each person on it. Personal use is free with no time limit; commercial, educational and non-profit use all require a purchased licence after a 30-day evaluation.

Where does each one run out?

The scoring is the same on both sides: five criteria, 10 points each, 50 in all, with every criterion counting once. Nothing sits behind a multiplier, so a total is the sum of its five marks and a reader can recompute it. The five are cost as teams grow, deployment footprint, support and maintenance, access control and audit, and multi-cluster reach, because those are the questions a Kafka interface is actually measured against after the first month: a second cluster, an access review with a date on it, an upgrade nobody owns, and a bill that moves when the team does. The widest gap between the two marks is on cost as teams grow, where AKHQ marks 10 and Offset Explorer marks 5. The marks come from the same matrix used on every comparison on this site, so a tool scores the same here as it does anywhere else, and the reason behind each mark is in the card below, under Why these scores.

The dependency figures in the cards below were read on 24 September 2026 from each project’s published release artefact and matched against the NVD and GitHub advisory databases, so they move whenever a release or an advisory lands. Kpow is self-hosted as well. What a licence buys here is not a different deployment model, it is a company under contract to ship the patched build.

AKHQ’s governance is present but shallow. Masking takes four modes, configured globally in application YAML and keyed on topic and field path, so what is hidden does not vary by who is looking, and only one filter per topic is supported.

Offset Explorer’s limits follow from being a desktop application. The documented authentication is client to broker only: plaintext, SASL, SSL with a truststore and OAUTHBEARER all authenticate the connection, and nothing authenticates a person to the application, which leaves no user identity for a role model or an audit trail to key on.

Which should you pick?

AKHQ is the pick where a platform team deploys once for everybody, because Offset Explorer installs on each engineer’s own machine and authenticates nothing about the person, so there is no identity for an audit trail to key on. Offset Explorer suits an individual engineer at 139 US dollars. For a shared, governed surface with an audit view, shortlist Kpow by Factor House at a published per-cluster price.

Pick AKHQ if:

• more than a handful of people need the view
• the people who need it should not all hold broker credentials
• there is more than one cluster to look at
• the cluster list and access model belong in source control

Pick Offset Explorer if:

• the work is one engineer’s and stays that way
• the payload formats are awkward and the search has to cover Protobuf and JsonPath
• diffing two clusters before a cutover is routine
• the team is under about ten engineers who all hold cluster access anyway

The line between them is not which interface is better. It is whether the thing the team needs is a service or an application. A personal tool becomes team infrastructure the day somebody who does not hold cluster credentials needs to look at a topic, and neither answers that day well: one has no user to attach a permission to, and the other names the user and still hides the payload by a global rule that is the same whoever is looking. Once that day arrives, Kafka RBAC tools covers the products that do attach a permission to a person, and the best Kafka management tools sets both of these against the wider field.

Kpow: the bill tracks clusters, not people

Neither of these prices the cluster. Offset Explorer bills per named user, so the number grows every time somebody new needs a topic browser, and AKHQ bills nothing on paper but takes the same growth out of operator time instead: somebody still sizes the JVM and reads the tracker before every upgrade. Kpow by Factor House is licensed per cluster at a published price, so the number doesn’t move when a team of five becomes a team of fifty: one stateless container, no external database, and up to 12 clusters from a single instance.

That’s the number worth watching as headcount changes. Run it against yours to see what stays fixed.
